"SPZCIFJZCATION forming part of Letters Patent No. 281,234, dated July 17, 1883.

- Application filed March 17, (No model).

To aZZ whom, it may concern:

Be it known that I, ISAAC F. BETTs, a citizen of the United States, residing at \Vilmington, in the countyof New Castle and State of Dela- 5 ware, have invented certain new and useful Improvements in. Fruit-Stoners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it apro pertains to make and use the same.

My invention relates to devices for stoning peaches, and relates particularlyto that class of devices shown in my-Patent No. 267,320, granted November 14, 1882.

My invention consists of constructions and combinations, all as will hereinafter be set forth.

Referring to the drawings, in which Figure 1 represents a front elevation, showing the relawith the uprights and part of the base broken away, showing in full line the relative positions of the parts when the plunger-rod has forced the peach below the knives, and the arm has forced the cross-head of the stonesupporting spindle to its lowest point preparatory to dropping the stones, the dotted lines showing the parts retracted preparatory to grasping the peach in the hopper; Fig. 3, a section on line w a", Fig. 2, showing the parts in top plan; Fig. 4, a side elevation with frame broken away; Figs. 5 and 6, detail views of the plunger; Fig. 7 a side elevation of part of the stone-supporting spindle, and Fig. 8 a side elevation of a modified 3 5 form of knife.

A represents the frame; B, the plunger; B, the cross-head for the plunger; Bathe jointed rod for moving the cross-head B; B, the crank for moving the rod; B, the secondary plunger. 40 O G are the pivoted knives; C C, the side stripping-knives; D, a frame pendent from the base; D, an adjustable and vertically-reciprocating anvil; D', a cross-head on the frame D; D, a lever attached by one end to the cross-head and by the other to a link, 13*; D an arm rigidly fixed to the base; E, aretractin g-sprin g attached by one end to the frame and by the'other to the leverl); G, ahopper attached to the uprights of the frame.

The frame A consists of base A, having an opening, a, uprights A A, and slotted top A The base is attached to the table A by means of bolts (1, arranged at suitable points. The uprights A A are bolted to the base, and are capped by the slotted top A. Pivoted to the front of the top is the crank 13, the pin If of which passes through the front wall of the slot a, and keyed to the upper section of the j ointed rod B The lower end of this rod is attached to cross-head B, which slides up 011 the uprights A A when the crank is revolved. Adj ustabl y attached to the center of this cross-head is the plunger B,which extends upwardly through an opening in the rear wall of slot (6. The lower end of the plunger is slotted, as shown at b in Fig. 5, so that'the knives G Owill not strike against the plunger when the latter is forced between them. 7 Near the upper end of slot I) is a head, b having its sides slotted to correspond with the slot 0, and for the same purpose. The head If is adjustably attached to the plunger, so that the distance from the lower end may be regulated when desired. The knives C O are pivoted to standards a c, which in turn are pivoted to lugs c c on base A. The knives 7 5 are forced together by springs C G", fitting on nipples a c" and for an obvious purpose. Hopper G is formed of two bowed pieces of metal, having the upper side flared for holding the peach, and their backs attached to arches G i, which extend to clips Gr G adjustably attached to the uprights A A bymeans of set-screws 5 The ends of the arches are held in place by screws 9'. The edges of the plates forming the hopper. are drawn together by means of springs G G, attached to arches G G. These springs permit the hopper-plates to separate and allow the peach to pass through when forced down by the plunger. The side stripping-knives, C O, are attached by their 0 lower ends to the wall of opening ain base A, and project upwardly on each side of the pivoted knives, as shown in my former patent.

Projecting upwardly through opening a is a vertically reciprocating anvil, I), which is 9 5 adj ustably attachedto a crosshead, D adapted to move upon the vertical bars of frame D. Theupper end of this anvil is slotted, as shown the latter.

in Fig. 7, so that the said anvil can pass upwardly between the knives against the under side of the peach resting in hopper G, and grasp the end of .the stone when the plunger is forced downwardly.

To the cross-head is pivoted one end of a lever, D, having its other end connected to the distal end of arm D by means of a link, D, pivoted at both ends to the objects to which it is attached. At or near the middle of the lever one end of the retracting-spring E is fixed. -This spring is attached by its upper end to one of the clips G and when retracted draws the inner end of the lever upwardly, and thus forces the crosshead D and spindle D toward the base. If desired, this spring may be dispensed with, and a spring, E, attached to the bottom of the anvil and under side of the frame; or, if desired, both springs may be used; but for ordinary purposes I pre-- fer to use the spring E, attached to the base and lever.

Upon the lever are inclined notches d, which serve as a bearing for the end of the secondary plunger B. This plunger is attached to the cross-head B by means of a set-screw passing through a sleeve, b", which may be attached at any point upon the cross-head, but is preferably attached in such a manner as to bring it parallel with the upright, so that when forced downward its end will strike the bottom of the inclined notches d on lever D and when the latter has been forced downwardly to its greatest distance will ride upon the bottom of the inclined notches d and force the cross-head of the plunger upwardly a sufficient distance to permit the lower end of the plunger to draw away from the stone, which will fall from the head of the stone-supporting spindle.

The operation of. the parts is as follows: The parts are drawn to the position shown in dotted lines, Fig. 2, so that the peach can be placed in the hopper G. The crank is now revolved, and forces the slotted end of the plunger, by means of jointed rod B" and crosshead B, against thetop part of the peach resting in the hopper, and penetrates to the stone, and its head If rests upon the surface of the peach. This head may be adjusted 011 the plunger to suit the varying sizes of the peaches, so that it will always rest upon the upper surface of In forcing its way to the peachstone the plunger impales the lower end of the peach upon the anvil, the slotted ends of which grasp said stone, and prevents it from turning. The peach in the meanwhile is being forced through the hopper, and between the pivoted and side knives, and stripped of its meat. secondary plunger, which strikes against the lever D, and forces the latter and the stonesupporting spindle downwardly, as shown in full lines, Fig. 2. \Vhen the cross-head D strikes against the bottom of the frame D, the lower end of said secondary plunger rides upon This operation is assisted by the the inclined bottom of notch d and elevates the plunger B a sufficient distance to release the stone, which falls through opening a. The plunger is now drawn upwardly, and the retracting-spring draws the anvil to the position shown in Fig. 1. If desired, the pivoted knives may be segmental, and have a retract-- ing-spring attached to one of the corners near the periphery, and to the uprights, as shown in Fig. 8. The operation of this knife is obvious.

I am aware that pcach-stoners have been provided with vertically-reciprocating anvils placedbeneath plungers, and to these, broadly, I make no claim; but

What I do claim is- 1. In a fruit-stoner, the combination of a frame, a slotted plunger moving upon said frame, a vertically-reciprocating anvil moving upon said frame,'and having a slotted end for the pivoted knives to pass through'when the anvil is reciprocated, said pivoted knives between the plunger and anvil, and strippingknives on each side of the rotary knives.

2. In a fruitrstoner, the combination of a frame, a plunger moving upon said frame, and having a slotted end'and a slotted head, and a vertical reciprocating anvil having a slotted end and placed beneath the plunger and knives, which latter are interposed between the plunger and anvil, said slots permitting the plunger and anvil, when reciprocated, to pass bev tween the knives.

3. In a fruit-stoncr, the combination of a frame, a plunger moving upon said frame, a secondary plunger operated by the main plunger, a vertically-reciprocating anvil having a lever operated by said plungers, and knives interposed between the plunger and anvil.

4. In a fruit-stoner, the combination of a frame, a plunger moving upon said frame, a secondary plunger operated by the main plunger, a reciprocating anvil beneath the plunger, a retracting-spring for the anvil, and knives interposed between the plunger and anvil, substantially as described. 5

5. I11 a fruit-stoner, the combination of a frame, a plunger moving upon said frame, a secondary plunger operated by the main plunger, a vertically-repiprocating anvil, a retracting-spring for, the spindle, knives between the plunger and spindles, and a hopper above the knives, substantially as described.

6. In a fruit-stoner, the combination of a frame, a cross-head having amain and secondary plunger, a cross-head having an anvil, a lever attached to the anvils cross-head and to the frame, and a retracting-spring for the anvil, substantially as described.
